空气污染特别是汽车尾气对城市空气的污染已到了非治理不可的程度。据调查,燃油汽车排放的尾气已成为上海人的无形杀手。上海人一年只能呼吸到22天新鲜空气,因此上海人的肺癌发病率高达十万分之五十七,成为全国肺癌发病率最高的三个城市之一。我国有10个城市被列入全球大气污染最严重的20个城市之列。研制电动车,实现汽车尾气“零排放”的环保工程,正受到政府的高度重视。电动车主要指电动汽车、电动自行车和电动摩
The air pollution, especially the pollution of urban air from automobile exhaust has reached a level that cannot be regulated. According to the survey, the tail gas emitted by fuel vehicles has become an invisible killer for Shanghainese. Shanghai people can only breathe fresh air for 22 days a year, so the incidence of lung cancer in Shanghai is as high as 57/100,000, making it one of the three cities with the highest incidence of lung cancer in the country. Ten cities in China are included in the list of 20 cities with the most serious global air pollution. The development of electric vehicles and the realization of “zero emission” environmental protection projects for automobile exhausts are being highly valued by the government. Electric vehicles mainly refer to electric cars, electric bicycles and electric motors
